New 2019 sound law in California
 

It's Kalifornia, good luck. It has nothing to do with sideshows. It has EVERYTHING to do with the people running that state. It will only get worse with the new governor.

I'm not sure there is anything "new" here as existing state law already has a db limit on exhaust systems that OEM mfgrs have to consider when selling cars in CA or elsewhere (95 db I believe).

Citations and stricter enforcement may have become more expensive however. Of course, a smog station with a careful eye can fail your car if it is determined that the exhaust is not OEM. Cats (e.g. 200 cell) that do not have a CA certified tag attached is an automatic fail.
Before a recertification, some pull their aftermarket exhaust and reinstall stock to get a recertification.
Bikers seem to ignore this as many have open exhausts that are way behind 100 db.
Feel free to chime in with corrections........

And this new referral program inspection is no joke. Go follow Alex Choi and what he is doing to his Lambo because a well known d#$khead BHPD couldn't give him speeding tickets or traffic violations so he nailed him with this new inspection deal. They don't just look for exhaust, you have to basically turn your car back 100% to stock as they will check for EVERYTHING, too include front license plate, window tint etc etc. Yes it is a money grab for the state, as usual. Have to fund the cell phones for the illegals since the texting tax didn't pass.

^^^I'm not defending the BHPD for their actions, but that little weenie Alex Choi and his YouTube buddies really pushed the cops into doing something. He pretty much kept f**king with them by shooting flames with his fart canons until something had to be done.

I'm setting a goal to have a property someplace out of Kalifornia to register my car before it comes due again in ~18 mos...not sure I will make it tho. This is early evidence the 'involuntary wealth transfer' process will accelerate under the new regime.

Of course, exhaust db level is arbitrary until measured at a referral program inspection. Cops will cite based on what they "think" is excessive db level. There are criteria established for a proper measurement in a specific environment as listed by the state. Maybe now, local muffler shops may create such a setup in order to stay in business.......... :rolleyes:

It's more BS from Kalifornia typically, POS state that just keeps trying to find ways to steal money from people living here. You'll probably have exhaust Manufacturer's gonna fight this soon or changing ways like having stamps on their exhausts to show certification of under decibel limits and is equal at OEM replacement. It's all a legal extorsion by Kalifornia, if you want to keep your performance exhaust you would have to go to a state referee, have them provide you a "Certificate of Compliance" ( At cost of course ). FN Commie state, can't wait to get out of this **** hole.

Just like the idiots who voted for increasing bridge tolls a dollar extra for the next 3 years, that's supposed to help with bay area road work, total BS as the gas tax and registration tax they implemented previously haven't done squat to repair roads in California and worst in Bay area full of potholes and crap. The money from those 3 programs goes to a general fund in which any politician can take money from. LOL. That bridge hike will just go to that general fund as well. Still waiting for California to fix the ****ty roads we have in the Bay Area.

Wonder if SEMA will fight this?

Does this affect those harley davidson bikes with open really loud exhausts?

of course not, those things can still ring you at 130 db

California law requires that all vehicles must be equipped with an adequate muffler to prevent excessive noise from the exhaust system. It also prohibits the operation of a passenger vehicle (other than a motorcycle), or a truck with a Gross Vehicle Weight Rating (GVWR) of less than 6,000 pounds, that has an exhaust noise level greater than 95 decibels, when tested under specified conditions. I should buy a Harley and just rev the fuk out of it everywhere.

LOL can't wait to see what the Harley guys have to say about this. :roflmao:

This is part 4 of AB1824, the first 3 having nothing to do with cars. I wonder what political shenanigans went on to get it tacked on?

I tend to agree, but the law itself allows over step of police if they deem it fitting which definitely sucks for everyone else. My exhaust is reserved, so I am not worried.

Its Kalifornia, land of the lawmakers and politicians that feel they are superior and know better than most. They also feel they should tell you how you should live and do things.:roflmao:

My GT3 is probably louder than 95 dB stock...

The part about being "subjective" is complete BS.

all you need to know.

The problem with socialism is you eventually run out of other people's money to spend.

Mods should sticky a thread for anyone to report getting popped for that. I'd be interested in how this will be enforced.
It'd be interesting to see what DBs different exhausts are on our cars as well.

Definitely not. My RS w/ BBi bypass is 96dB at idle.

And you California guys should be happy you don't live in British Columbia, where our law mandates cars can't be louder than 83dB (which essentially renders all F-Types, Huracans, etc. "illegal" in the eyes of our local government).

Dumb law.

Yeah so your car would fail the test. Mine has BBi too. So yeah, don't know what the SPL is stock but with the center bypass it's pretty loud.

BTW, the test isn't at idle. The test is with the car holding a certain RPM.

You're right. My mistake. I'm 99% certain my car was 96dB at 2,500 RPM (or thereabouts).

The exhaust is sound-tested at 3000 RPM for cars produced before 1972 and at 3/4 maximum RPM for cars after that.
